Cat-scratch disease presenting as a solitary tumour in the breast: report of three cases.

Cat-scratch disease (CSD) may appear as a solitary mass in the breast and give the impression of a breast carcinoma. In this case, further clinical and laboratory investigation is required to rule out malignancy. We present three cases of CSD of the breast in women of 64, 31 and 61 years old. Each presented with enlarged lymph-nodes in the breast, which were clinically mistaken for solitary tumours. In the first two patients, the mammography was negative. The third patient had a mammogram which indicated a well-defined solid mass in the parenchyma without calcifications. We discuss the clinical, histological and histochemical findings, analyze the differential diagnosis and review the literature.

Antibiotic therapy for cat-scratch disease: clinical study of therapeutic outcome in 268 patients and a review of the literature.

During 24 months in an uncontrolled, retrospective study of 268 patients with cat-scratch disease (CSD), 202 were treated with 18 different antimicrobial agents. Criteria for antibiotic effectiveness were established. One or two antibiotics were taken separately for at least 3 to 5 days by 202 patients with CSD. Outcome was determined by follow-up examinations and telephone. Effectiveness of antibiotic therapy was based upon 3 or more days of therapy and clinical improvement of the patient with absence of and/or a decrease in malaise, fatigue, fever, headache, anorexia, lymphadenopathy and, in 90 patients, a declining or normal sedimentation rate. Of 18 different antimicrobials prescribed, 14 commonly used antibiotics were judged to be of little or no value in treatment of CSD. Four antimicrobials were efficacious. Efficacy of the three oral drugs in decreasing order was: rifampin 87%, ciprofloxacin 84%, trimethoprim-sulfamethoxazole 58%. Gentamicin sulfate intramuscular was 73% effective. Antibiotic therapy can be considered for patients with severe cat scratch disease. Conservative, symptomatic treatment is recommended for the majority of patients with mild or moderate CSD.

Cat-scratch disease. Subtle vertebral bone marrow abnormalities demonstrated by MR imaging and radionuclide bone scan.

Cat-scratch disease (CSD) is a benign, self-limited cause of lymphadenitis occurring mainly in children and young adults. Its etiology is a delicate, small gram-negative pleomorphic bacillus. Less common manifestations of CSD are seen in 5% of patients and include Parinaud's oculoglandular syndrome (with enlargement of the preauricular nodes), parotid gland enlargement, encephalitis, radiculopathy, pneumonitis, erythema nodosum, thrombocytopenia, and lytic bone lesions. We describe a patient in whom magnetic resonance imaging initially detected subtle vertebral bone marrow abnormalities that correlated with the site of abnormality on a subsequent radionuclide bone scan.

Bone infection in cat-scratch disease: a review of the literature.

OBJECTIVE: To describe the main features of bone infection associated with Cat-scratch disease (CSD). METHODS: We searched for articles indexed in the international literature databases by using the following key words: "Bartonella", "bone", "cat-scratch", "osteomyelitis" and "osteolytic". RESULTS: Cases of 47 patients were reviewed. The median age was 9 years, with an equal sex distribution. Bone pain and fever were the main symptoms. The presence of fever and increased age were more common in patients with bone infection than classically reported in uncomplicated (i.e. nodal) CSD. The vertebral column and pelvic girdle were the most common sites of infection. Radiological examination typically confirmed bone osteolysis. All patients recovered without complications or chronic infection, although they received a various combination antibiotic regimen and duration therapy. The mechanism by which infection might spread to the bone is via the haematogenous route, accounting for most of the disseminated cases and via the lymphatic route, for those with regional limited extension. CONCLUSIONS: Bone infection is rare but should be considered when bone pain and fever are present in a patient with nodal CSD. The prognosis is good, whatever treatment is given. Thus bone biopsy should be recommended only in a difficult diagnostic setting, when other bacteria or malignant disease are suspected.

Serological study of Bartonella henselae in cat scratch disease in Japan.

It has become clear that Bartonella henselae is a common cause of cat scratch disease (CSD). The indirect fluorescence antibody (IFA) test for detection of IgG and IgM antibodies to B. henselae concerning CSD showed that 5 (50%) of 10 patients with CSD had a serum IgG antibody titer of 1:128 or more and that 2 (20%) patients had a serum IgM antibody titer of 1:20 or more. One of 7 asymptomatic members of patients' families (14%) had IgG antibody to B. henselae at a titer of 1:256. IgM antibody to B. henselae was not detected in sera from the patients' families. Both IgG and IgM antibodies to B. henselae were not detected in sera from the healthy control group. These data suggest that B. henselae may be a cause of CSD in Japan.

Epithelioid angiomatosis or cat scratch disease with splenic and hepatic abnormalities in AIDS: case report and review of the literature.

Cat scratch disease (CSD) in the setting of HIV infection is associated with lesions of epithelioid angiomatosis but not with granulomatous lesions seen in the normal host. We report a case of CSD in a patient with AIDS and Kaposi's sarcoma with epithelioid angioma of skin, thrombocytopenia, and abnormalities of liver, spleen, lymph node, and pleura that responded to antimicrobial therapy. We also review reported cases of epithelioid angiomatosis in HIV infections. 12 of these resolved, including 3 without antimicrobial therapy; 18 demonstrated pleomorphic organisms with Warthin-Starry silver stain. Six involved visceral or bony as well as skin lesions. CSD should be considered in the setting of HIV infection with skin nodules even in the presence of biopsy-proven Kaposi's sarcoma. CSD may in these patients be responsible for a variety of disseminated lesions which respond to antimicrobial therapy.

[Cause of unusual unilateral vitreous hemorrhage: neuroretinitis of Cat-Scratch disease. Presentation of a case].

A 49 years old woman presents an unilateral decrease of vision. An important vitreous hemorrhage obscures the fundus. After partial resorption a typical aspect of neuroretinitis is seen: macular and disc edema with macular star formation. Cat-Scratch disease is suspected after general examination of the patient. This diagnosis will be confirmed by the laboratory investigation. This disease is not so rare and represents one of the principal causes of neuroretinitis. The vitreous hemorrhage can be due to vascular insult by the bacterium responsible for Cat-Scratch disease which one has an important tropism for endothelial cells and can be responsible for vascular occlusive phenomena. Clinical signs, treatment and evolution of this disease are going to be discussed in this article.

An analysis of lymph node DNA for possible bacterial agents of cat-scratch disease.

Recent investigations have implicated Afipia felis and Rochalimaea henselae as possible agents of cat-scratch disease (CSD). We studied lymph nodes with necrotizing granulomas characteristic of CSD for A. felis and R. henselae DNA so that the relationship of these organisms to lymph nodes with necrotizing granulomas of unknown etiology might be better defined. We examined formalin-fixed, paraffin-embedded lymph node biopsies with necrotizing granulomas suggestive of CSD from 28 children obtained over the last 10 years. None had identifiable bacteria, fungi, or acid-fast organisms on routine staining. Pleomorphic bacillary structures consistent with the CSD bacillus were seen with the Steiner stain in 17 cases. We performed the polymerase chain reaction (PCR) on the extracted lymph node DNA with DNA primers for these organisms after demonstrating the presence of amplifiable DNA with c-K-Ras primers. R. henselae was identified in two samples. A. felis DNA was found in just one specimen. These putative CSD bacteria are infrequently associated with necrotizing granulomas using standard PCR techniques. It is possible that some of the patients did not have clinical CSD. The preservation of DNA or numbers of bacteria in the extracted sections may be inadequate for demonstration by DNA amplification methods. These bacilli may be responsible for a small proportion of these characteristic lesions of unknown etiology, or the typical CSD histology, including the presence of pleomorphic bacillary structures, may be nonspecific.
